I just changed out my first coil on the STM. Swapped a spent 0.5 for a new Kanger OCC 0.5 This thing is spitting way too much. I even have a screen in my drip tip. Could this be a bad coil? Nothing else was changed. It's very annoying.
It could easily be a bad coil, they do happen. Generally, when the coil spits the deck is flooded. It could also not be tight or missing an o-ring.
